Miniature power transmission line galloping monitoring device based on CORS system

Abstract

The utility model discloses a miniature power transmission line galloping monitoring device based on a CORS system, and the device comprises an insulated circular line card, a movable tightening bolt,a measuring unit fixing plate, a fixing bolt, a protective box, a lithium battery, a single-chip microcomputer system, a GNSS receiving module, a ZIGBEE wireless communication module and a CDMA / GPRScommunication module. The insulated circular line card is connected with the measuring unit fixing plate through the movable tightening bolt, and the measuring unit fixing plate is arranged at the topof the protective box by the fixing bolt. The lithium battery, the single-chip microcomputer system, the GNSS receiving module, the ZIGBEE wireless communication module and the CDMA / GPRS communication module are disposed in the protective box. According to the invention, the device is based on a regional CORS satellite positioning system, and employs the GNSS receiving module for receiving satellite signals, and communicates with a CORS continuous operation base station through the CDMA / GPRS communication module, solves and obtains the high-precision position information in real time, can obtain the real-time deviation of a transmission line, can measure the influence of the deviation displacement on a transmission line insulator, and realizes the all-weather monitoring and prevention ofthe tripping of the power transmission line.

Description

technical field [0001] The present application relates to the field of power monitoring, in particular to a CORS system-based micro-transmission line galloping monitoring device. Background technique [0002] In recent years, with the increasing demand for power transmission, various ultra-high voltage and large-span transmission towers have been continuously put into construction and use. Such large-span transmission towers are usually built The wind field acceleration effect caused by the complex terrain and landform has a very serious adverse effect on the wind resistance performance of the transmission tower; the wind field of the mountainous terrain is different from the wind field of the flat landform, and the complex terrain of the mountainous area will significantly change the wind flow near the ground. The distribution of wind speed in the vertical direction and the turbulence structure form the unique wind field structure characteristics of mountainous terrain, suc...
